That side of the PSU power cables will be unfused- or at least, fused on the AC supply side of the PSU which will happily set low voltage wires in fire before popping.
Yes you can hook them there, but you MUST add an inline fuse of some form to the fan leads.

Would that still cause a fire?
Would I connect both positive and negative to it?
Also would it just be better for me to use one of these amazon.com/…/ref=ppx_yo_dt_b_asin_title_o00_s00?i… with a laptop charger?

You would connect both positive and negative of your fan to the PSU rail, but the positive side to the fan would need the inline fuse.
You can connect it without a fuse, it’s just risky and I discourage doing that.
Those connectors would work for a secondary supply if your laptop charger is 12 volts. Most laptops charge at voltages higher than that though (15 to 20v is typical range) so read the charger spec carefully.

A quick search for 2 channel 24v fan controller yealded the below link. Not saying this is ideal for your scenario but something similar will work and can be powered with a power brick. Doesn’t look like it comes with instructions though so I’m not sure what current it requires. The temperature sensor could work to make it turn on when the printer heats up as well.
